Abstract
An amplifier includes an input stage. The input stage includes a differential pair and a load circuit. The differential pair includes a first transistor and a second transistor. The first transistor and the second transistor are configured to amplify a received differential signal. The load circuit connects the differential pair to a reference voltage. The load circuit is configured to vary in resistance in inverse proportion to the transconductance of the first transistor and the second transistor.
